What does the Dbcli Procedure skill do?

Manage stored procedures, functions, and triggers (CREATE/ALTER/DROP operations) It is listed under Coding & Dev Tools on SkillMD.

Is Dbcli Procedure safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

DbCli Procedure Management Skill

Command Style (Use PATH)

All examples use the plain command name dbcli (no directory prefix). Ensure dbcli is on PATH instead of hardcoding paths like .\.claude\skills\dbcli\dbcli.exe.

Overview

Manage stored procedures, functions, and triggers using DbCli's DDL and EXEC commands. This skill covers creating, altering, executing, and dropping database programmability objects across multiple database systems.

Safety Level: Critical
Requires Backup: Mandatory before DROP operations

Quick Start

# ⚠️ CRITICAL: Always backup before DROP operations!
# Backup all procedures/functions/triggers
export DBCLI_CONNECTION="Server=.;Database=mydb"
export DBCLI_DBTYPE="sqlserver"
dbcli export-schema all -o backup_schema.sql
# Or backup specific type
dbcli export-schema procedure -o backup_procedures.sql

# Create a stored procedure (SQL Server)
dbcli ddl "
CREATE PROCEDURE GetUserById @UserId INT
AS
BEGIN
    SELECT * FROM Users WHERE id = @UserId
END"

# Execute stored procedure (parameterized)
dbcli procedure "GetUserById" -p '{"UserId":1}'

# Drop procedure (with backup)
dbcli ddl "DROP PROCEDURE IF EXISTS GetUserById"

# Restore from backup if needed
# Extract and execute the CREATE statement from backup_procedures.sql

# List all procedures
dbcli query "
SELECT name, create_date, modify_date 
FROM sys.procedures 
ORDER BY name" -f table

Command Syntax

# Set environment variables first:
# export DBCLI_CONNECTION="connection-string"
# export DBCLI_DBTYPE="database-type"

# Create/Alter/Drop
dbcli ddl "<PROCEDURE_DDL_STATEMENT>"

# Execute procedure (non-query)
dbcli procedure "<PROC_NAME>" [-p JSON] [-P params.json]

# Execute procedure and return result set
dbcli procedure-query "<PROC_NAME>" [-p JSON] [-P params.json]

Notes:

procedure / procedure-query accept input parameters only. Output parameters/return values are not surfaced by DbCli.
procedure-query returns a single result set. For outputs, add explicit SELECT in the procedure or use exec with SQL.

Options

Option	Alias	Description	Example
`--db-type`	`-t`	Database type	`-t sqlserver`, `-t mysql`, `-t postgresql`
`--format`	`-f`	Output format	`-f json`, `-f table`
`--file`	`-F`	Read SQL from file	`-F create_procedure.sql`
`--params`	`-p`	JSON parameters object	`-p "{\"Id\":1}"`
`--params-file`	`-P`	Read JSON parameters from file	`-P params.json`
`--config`		Use config file	`--config <path>`

Core Operations

1. Stored Procedures

    @Status VARCHAR(20),
    @Limit INT = 100
AS
BEGIN
    SET NOCOUNT ON;
    SELECT TOP (@Limit) id, name, email, status
    FROM Users
    WHERE status = @Status
    ORDER BY created_at DESC
END"

# Procedure with output parameter
dbcli ddl "
CREATE PROCEDURE dbo.GetUserCount
    @Status VARCHAR(20),
    @Count INT OUTPUT
AS
BEGIN
    SELECT @Count = COUNT(*) 
    FROM Users 
    WHERE status = @Status
END"

Execute Procedure

export DBCLI_CONNECTION="Server=.;Database=mydb"

# Execute without parameters
dbcli exec "EXEC dbo.GetActiveUsers"

# Execute with parameters
dbcli exec "EXEC dbo.GetUsersByStatus @Status='active', @Limit=50"

# Execute with output parameter
dbcli exec "
DECLARE @UserCount INT

SELECT @UserCount AS ActiveUserCount"

Safety Best Practices

🛑 Critical: Always Backup Before DROP

# 1. Export procedure definition
dbcli query "SELECT OBJECT_DEFINITION(OBJECT_ID('dbo.ImportantProc'))" > backup_proc.sql

# 2. Then drop
dbcli ddl "DROP PROCEDURE dbo.ImportantProc"

⚠️ Test in Development First

# 1. Test in development
export DBCLI_CONNECTION="Server=dev;Database=mydb"
export DBCLI_DBTYPE="sqlserver"
dbcli ddl -F new_procedure.sql

# 2. Execute tests
dbcli exec "EXEC TestNewProcedure"

# 3. Deploy to production
export DBCLI_CONNECTION="Server=prod;Database=mydb"
dbcli ddl -F new_procedure.sql

✅ Procedure Development Checklist

Document procedure purpose and parameters
Use descriptive naming conventions
Add error handling (TRY...CATCH, EXCEPTION blocks)
Include transaction management where appropriate
Test with various input scenarios
Backup existing procedure before ALTER/DROP
Review execution plan for performance
Grant appropriate execute permissions

Dynamic SQL (PostgreSQL)

export DBCLI_CONNECTION="Host=localhost;Database=mydb"
export DBCLI_DBTYPE="postgresql"
dbcli ddl "
CREATE OR REPLACE FUNCTION dynamic_query(table_name TEXT, column_name TEXT)
RETURNS TABLE(result JSONB)
LANGUAGE plpgsql
AS $$
BEGIN
    RETURN QUERY EXECUTE format('SELECT row_to_json(t) FROM %I t WHERE %I IS NOT NULL', table_name, column_name);
END;
$$"

Troubleshooting

"Procedure already exists"

# SQL Server - Use CREATE OR ALTER
dbcli ddl "CREATE OR ALTER PROCEDURE dbo.MyProc AS BEGIN ... END"

# MySQL - Use DROP IF EXISTS first
dbcli ddl "DROP PROCEDURE IF EXISTS MyProc"
dbcli ddl "CREATE PROCEDURE MyProc() BEGIN ... END"

"Insufficient privileges"

# Grant EXECUTE permission
dbcli exec "GRANT EXECUTE ON dbo.MyProc TO UserName" -t sqlserver
